My network connection completely died - "failed: 49 - Can't assign requested address"

The entire networking stack on my 2012 Retina MBP died just a few minutes ago, and I was only able to get it up and running by rebooting.

First no sites in Safari worked and then I noticed when using telnet that:

[stig@Hyperion:~]$ telnet www.allthingsd.com 80

Trying 192.0.65.213...

telnet: connect to address 192.0.65.213: Can't assign requested address

Trying 192.0.65.216...

telnet: connect to address 192.0.65.216: Can't assign requested address

telnet: Unable to connect to remote host

Strangely enough traceroute and ping worked.

In the system log there is no warning untill the network is down:

I tried flushing the routes and using ifconfig to down/up the interfaces but nothing worked.

Has anybody seen anything like this?

MacBook Pro with Retina display, OS X Mavericks (10.9)

Some updates. I can't seem to keep my system up continuously at the momement. It tends to throw a kernel panic when I wake the machine from sleep. The best uptime I have had since the problem last occurred was about 7 days. A periodic check of netstat showed nothing unusual during that time. This problem seems to only occur at longer uptimes ( > 21 days).

I am leaving my system up (without cpu sleep) running bittorrent to see if I can cause the bug to appear again.

Nov 25, 2013 11:48 AM in response to meople

I I forced keepalive to on and set all the expire times to 1. Naturally, it had no effect, maybe because these connections are orphans. That's why I asked about minimum values for which lower values might be ignored by the OS.

Still, someone should post output of sysctl for a pre-mavericks system.

Same problem here on MBP 2010 with maverick.

I'm curious to know if people that are having this issue have set their computer to sleep during its uptime.

I definitely agree that this issue doesn't show unless you've been up for a long time (3wk+) because there are a lot of sockets (65k+, but OSX only allocates a few thousand of them as dynamic connections) to exhaust before you run out.

I suspect it may have to do with sockets not being released on sleep, and not being reacquired on wake, so they leak.

Reasonable theory. Both of my computers are going to sleep.

I have two Mini's at home which I do put to sleep. So far it has not happen with any of these. The one I'm typing this on right now has an uptime of 34 days and 13 hours.

The 2012 Retina MBP I use at work is never put to sleep, and it was with this one I experienced it.

Yes, it goes to sleep.

The problem started on Nov 25th, and the laptop was rebooted on Nov 4th (after Maverick update). So, about 21 days.

Nov 26, 2013 11:24 AM in response to otodic

Just making sure, you guys have specifically set the Mac to not sleep in power settings? By default, OSX is configured to sleep after 10min (or 15? i forget) of inactivity, and hibernate after some longer amount of time. Waking from sleep is fast enough to be imperceivable from just having the display turn off.

You know what, after you said this I went back and checked. I said that my computer is going to sleep, but I misspoke - I do have my energy saver settings set to "Never" sleep, I'm just turning the display off. So mine are not going to sleep.

One more point that may or may not be relevant, on my home computer I stay logged in all the time, at work I log out every night.

Same here. Mac mini mid 2010. Sleep disabled. 11 days uptime. Updated from 10.8. Closing Chrome, Skype and Fusion helped for several minutes...

Is anyone else here using Dropbox?

I noticed right now with netstat and lsof that Dropbox<->Finder has a heck of a lot of established connections.

Take a look at this (PID 26164 is dropbox)

[stig@Hyperion:~]$ sudo lsof|grep 26164

I don't know but I don't think Dropbox should use so many TCP connections - unfortunately I rebooted my Mac at home today so I can't compare.

But all of a sudden Spotify and the Cisco VPN adapter started to act up, and it all returned to normal once I relaunched Dropbox and restarted (killall) Finder...

Dec 10, 2013 6:42 AM in response to StigBull

interisting, StigBull - yes, I am using DropBox on both of my machines. But, I've been up for 14 days and only have 4 TCP connections attributed to my DropBox proc id.

My network connection completely died - "failed: 49 - Can't assign requested address"
